摘要:
The present invention relates to a device in the form of a suction nozzle (10) for an urban or industrial aspirator (1), preferably self-propelled, comprising a rigid hose or tube (1000), said rigid hose or tube comprising gripping means (100, 200, 300) that comprise a first gripping element (110, 210, 310) in the form of a handle, a support element (120, 220, 320) serving as a lever, and a second gripping element (130, 230, 330) and optionally a base (101, 201, 301).
摘要:
An apparatus for and a method of preventing bumping and falling of an automatic travelling cleaner wherein a situation of the cleaner is determined by sensing a variation of flow rate of a fluid in an extension pipe depending on a gap between an intake port and a surface to be cleaned, thereby deriving a suction work ratio or sensing revolutions and a current value of a cleaning motor or a torque value of each travel motor, and then determining a travel, a bumping, and a step sensing, based on the sensed value. The present invention eliminates the provision of a plurality of sensors densely arranged around a cleaner and adapted to sense bumping and falling of the cleaner and thus eliminates the requirement of additional devices for the sensors. This reduces the manufacture costs.
